Re: [Discuss-gnuradio] Problem using GRC when executing the grc examples

[Josh Blum]

Just to clarify, this problem with the examples has nothing to do with 
.bashrc. Nevertheless, it is good to understand the .bashrc when working 
on a unix system (specifically one with bash).

For your installation, just save the .grc file to a writable directory.

For the future: I just pushed a branch that will generate the python 
file in your system's temp directory should the default directory be 
read-only.
